Embodiment Construction

[0016] figure 1 The free-hanging tube pump shown has a motor 1 whose gravity and reaction forces are guided by a lantern-shaped support 2 into a base 3 which also receives the forces of the pump part 4 . The multi-layer lantern 2 comprises a motor lantern 2 . 1 which surrounds the axial bearing 5 of the shaft 6 and the coupling 7 of the shaft 6 . The motor lantern 2.1 is supported by the middle lantern 2.2 on the elbow box 2.3 formed inside the lantern 2 in an airtight manner. The weight of the motor 1 is introduced into the base 3 from the base plate 2.4 of the elbow box 2.3.

[0017] For those applications where the gravity of the motor 1 is too high, the motor lantern 2.1 can also be configured as a so-called push-out lantern (überstülplaterne), which pushes through the middle lantern 2.2 and the elbow box 2.3 , and wrap both with the larger diameter. This push-rod lantern also distributes the force of the motor 1 onto the base 3 directly in the plane of the base plate ...

Abstract

The invention relates to a tubular pump whose running and guiding device is connected by an ascending pipe (9) provided with a shaft (6) which is mounted therein for actuating said running device and is connected to a drive unit (1) arranged thereabove. A multisectional lantern (2) transmits the weight of the drive unit to a base (3). A known bearing element (17) is mounted on the ascending pipe (9, 9.1) and / or on an elbow (15), the ascending pipe leading to a pressureproof elbow housing (2.3). A base plate (2.4) of said pressure-proof elbow housing (2.3) is provided with a force-transmitting receiving element, a guide and a seal for the bearing element (17).

Description

technical field [0001] The present invention relates to a tube pump ( ), its operating mechanism and guiding mechanism are connected with a vertical pipe, wherein a shaft for driving the operating mechanism is arranged in the vertical pipe, and the shaft is connected with the driving device arranged above the vertical pipe, and a multi-layer lantern-shaped bracket (Laterne ) transmits the gravity of the drive unit to the base, an external bearing element is mounted on the riser and / or bend and the riser opens into an airtight bend box. Background technique [0002] Tube pumps of this type are known, for example, from the KSB Centrifugal Pump Dictionary, 3rd edition, July 1989, page 262. They are usually of a single stage configuration and are used to convey large fluid volumes, where an axial or semi-axial impeller is often used as the rotor. A guide mechanism is installed behind the rotor, and the guide mechanism leads into one or more vertical pipes, by means of the gui...
